Binder-frame.



FREDERICK GRIMME, OF CHICAGO, ILLINOIS.

BINDER-FRAME Specification of Letters Patent.

Patented May 25, 1909.

Application filed June 22, 1908. Serial No. 439,742.

To all whom it may concern:

Be it known that I, FREDERIOK GRIMME, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented new and useful Improvements in Binder-Frames, of which thefollowing is a specification.

This invention relates to loose leaf binder frames for holding ledgerand other leaves, circulars, catalogues, etc., and its object is toprovide a frame of simple and inexpensive construction adapted toreceive and hold the leaves secure and evenly and permit them to beeasily inserted or removed.

Further objects of the invention are to provide a binder frame with around back; to cause the stub ends of the leaves to spring up like aspring back book and the leaves to lie flat when the book is opened; andto provide simple means for adjusting the book.

l/Vith these and other objects in view the invention consists of certainimprovements on the frame disclosed by my Letters Patent No. 796,322dated August 1, 1905 and which will be fully pointed out hereinafter inthe detail description of the accompanying drawings, in which Figure 1is a plan view of the binder frame. Fig. 2 is a sectional view on theline 22 of Fig. 1. Fig. 3 is an enlarged detail sectional view. Fig. 4is an end view showing the locking mechanism. Fig. 5 is a sectional viewon the line 5-5 of Fig. 4. Fig. 6 is a detail sectional view of therubber head.

In the drawings, 7 designates the back of the book which is made ofresilient material in the shape of a round-back book. The covers 8 arehinged to the back in any manner familiar to book binders but preferablyby means of the covering 9 which may be made in one piece to cover theback and cover boards, as shown in Fig. 2.

A center plate 10 having upturned ends 10 is arranged centrally withinthe back and a plurality of yielding spring steel connections 11 areadjusted to said center plate. Clamping plates 12 having inwardlyprojecting edges 12 to engage the leaves (not shown) are mounted on theends of the yielding connections. The clamping plates are bent to form asocket 13 to receive a pivot pin 13 which rests in said socket andengages hinge members 14 fastened to the covers and projecting outwardfrom the covers through openings 15 in the clamping plates. Thus thecovers are hinged to the frame and the clamping plate constitutes onemember or leaf of the hinge and the parts 14, which are fastened to thecover board, constitute the other member of the hinge. These hingemembers 14, project through the openings 15 in the clamping plates toaline with the socket grooves 13 so that the pivot pins 13 may bereadily inserted or removed.

Two rollers 16 of the same diameter are mounted in parallel relation inthe ends of the center plate and are provided with intermeshing gears 17so that they will rotate together. One of the rollers is provided withan extension 18 to receive a key. Tapes 19 are fastened at their ends tothe rollers and they pass over guide rollers 20 which are mounted onpins 20 arranged in socket 21 in theclamping plates.

It will be observed that the clamping plate is bent to form the socket13 on one side to receive the pivot pin 13 and also to form the socket21 on the other side to receive the guide roller pin 20. The springconnections 11 are extended up to overlap the pins 20 (Fig. 3).

The tapes are preferably fastened to the rollers in some mannerinteriorly thereof to avoid providing a projection on the surface of theroller which might have a tendency to make the rollers wind unevenly. Ihave shown one way of accomplishing this result in the drawings in whichthe rollers are provided with longitudinal slots 22, the ends of thetape being inserted in said slots, after which the roller is clampedupon the ends of the tape by a hammer blow or pressure.

The rollers are locked in adjusted position by a locking dog 23 whichengages a ratchet wheel 24 on one of the rollers. A spring 25 operateson the locking dog to hold it in engagement with the ratchet wheel andin the particular construction illustrated in the drawings the dog islocated on one side of the end 10 of the center plate and the spring 25on the other side. The dog is provided with a projection 26 whichextends through a slot 27 in said plate to be engaged by the spring 25.The dog is released from engagement with the ratchet wheel by a cam 28carried by a push bar 29 which is supported in brackets 30, 3.0. on. theend 1'0.. This camis normally held out of operative engagement with thedog by a spring which may be in thevform; of a coil spring 31 located onthe push bar between the end 10 and the bracket 30 and bearing againstthe cam 28 (Fig. 5).

may provide heads 32 made of rubber or other suitable material at theends of the back 7. These heads are shown in Fig. 1 and in broken linesin Fig. 2 and a detail section isshown in Fig, 6 The heads are fastenedto the back of the book, at the ends thereof, in any suitable manner,and they preferably overlap. the same to form the projections 33 onwhich the book may rest. These heads are divided into sections so thatthe back of the book may be extended or contracted as required.

Braces 3 4;, preferably of the same material as the connections 11, are,fastened to the clampingplates adjacent to said connections and extendapproximately to the center plate. These braces tend to push the middlepart of the back down as the edges are drawn together when the rollersare turned to wind the tapes thereon.

I" may use a leaf made as disclosed in my Letters Patent No. 767 ,940dated Aug. 16 1904 or any other leaf which is or be adapted to thisbinder.

My improved binder frame is light in weight but strong and substantial:in con.- struction and comparatively inexpensive to manufacture. Eachframe is capable of. adjustment to hold a greater or less number ofleaves and; at all times the binder will hold the leaves regardless ofthe number evenly and properly in place. The construction is such thatwhen the book is opened the stub end will spring up like a spring backbook andthe leaves will lie flat and close together at the. pointstherein without spreading and exposing the tapes in the manner set forthand described niorefully in my Patent No. 796,322 hereinbeforereferredto. When it is desired to insert or remove a leaf or leavesthelocking dog is released by pushing the push bar in and then theclamping plates may be spread apart as far. as desired. After the leafis inserted or removed the rollers are woundup, to tighten the clampingplates on the stub ofthe book by applying a key to the projection 18.The hinge members 14 are made of metal in. any suitable manner and arelocated on the inner sides of the covers so that the outer side of thecovers will be perfectly fiat. A removable canvas cover may be used onthe book and this cover will conform to the back of the book whether.the back is extended or contracted to receive a large number or a fewleaves. I may use aremovable key, as heretofore mentioned, or a per-vmanently attached key on the projection1'8.
